I have a 1997 Wolverine. I went to go riding yesterday and it started right up, I drove it off the trailer and had it sitting there running while I put the ramps and tie down straps away. All of a sudden the wheeler died. I was thinking that the thing had just choked out, but after that it would never re-start. I checked the fuel and it was good. Checked for spark and it is there. Any one have any ideas on what could have happened while it was running to cause this problem?
